So, this has happened to me multiple times now, and to be honest it's getting frustrating as a casual user of this particular SE (especially since the judgements seem less cut-and-dried than other SE's I'm on).
I have a really hard time figuring out whether a partial answer should be a comment or a new answer. I've had both versions deleted multiple times no matter how I word them.
To be a bit more clear, in cases where there are questions that are a bit lengthy and perhaps have multiple issues embedded in them, answerers frequently post perfectly reasonable answers that cover most of the issues. I come along and have thoughts that could cover some of what I think haven't been covered, so I want to add those thoughts b/c I think they may be useful.
In the case where I tried adding that to a comment, it was deleted by a moderator with a note telling me I shouldn't post an answer (even an incomplete answer) as a comment.
In the case (different question) where I tried adding my thoughts as a new answer (acknowledging that other people had answered everything else), I got downvoted to and flagged for deletion for not answering the question.
I really don't understand how I'm supposed to handle a partial (but in theory additive) answer, given those examples. Should every answer rehash everything covered by existing answers?
